What we don't know was just how pervasive ex-attachment is, so we conducted a poll to find out.

Over 1,000 people took the survey and the results astounded us. People are much more attached to their exes than we realized, and ex-obsession affects people in every love stage, not just singles and those who have recently broken up or divorced.

Below are some of the fascinating breakup statistics and results from our survey:

Seventy-one percent of people say they think about their ex too much. Narrowed to singles, the figure goes up to 81 percent. More than half (57 percent) of singletons say thinking about their ex prevents them from finding new love.

But it's not just singles — married folks are ex-obsessed as well. Almost two-thirds of married people (60 percent) agree that their ex is on their mind too often, and 36 percent say their attachment to their ex interferes with their marriage.

Seventy-four percent of women and 64 percent of men think about their ex too much. Seventy-six percent of women and 70 percent of men have looked up an ex on the internet. And 50 percent of women and 40 percent of men say they look at their ex's Facebook or other online profile too often.

3. Digital technology plays a major role in the struggle and hinders people from moving on.

Fifty-nine percent of people remain Facebook "friends" with an ex after they've broken up, and 48 percent (including 42 percent of married folks) say they look at their ex's Facebook page or other social networking profile too often. Likewise, almost three-quarters of people (74 percent) have looked up an ex on the internet.

In one of the most shocking breakup statistics, we found that 86 percent of people admit to looking at photos of their ex; 14 percent of married folks admit to doing so often. And 50 percent people have called, texted, emailed or IMed an ex when they shouldn't have (Uh, can you say drunk dialing?).
